National Summary

Tonight

Tonight will be cold and generally dry with clear spells. Lowest air temperatures ranging -1 to plus 2 degrees with patches of frost and fog forming and with a risk also of some icy patches. However it may stay cloudy through the night in the north and east with patchy drizzle.

Tomorrow

Tomorrow, Friday: Another generally dry day in store with sunny spells in most areas but there is a possibility that the cloud will persist in parts of the east and north. Rather cold with a frosty start for many and top temperatures of 5 to 8 degrees in light breezes.

Outlook

General: Cold but mainly dry this weekend. Day time temperatures will be in single figures. There will be significant frosts at night, under any clear spells, with temperatures a few degrees below zero. But the trend into next week, is for temperatures to recover both by day and by night. Southerly winds will freshen gradually and there will be some rain moving in off the Atlantic eventually.Cold on Friday night, with a widespread frost, severe in places and some icy patches. Lowest temperatures plus 1 to -3 C. It'll be a largely dry night once again with light southeast winds and clear spells and with some patches of mist and fog locally. Saturday and Sunday will both be mainly dry days, with some sunshine at times, but cold each day, with top temperatures generally just 3 to 7 C. The nights will be very cold, with sub zero temperatures quite widely and as low as -3 or -4 C., in places. So hard frosts both nights and with the frost slow to clear from some areas each morning. A few mist or fog patches may form also. But on Saturday night and on Sunday morning, some patches of drizzle are likely to encroach into some Atlantic fringes, but it should hold dry elsewhere. Current indications suggest that temperatures will recover gradually early next week, both by day and by night. Southerly winds will freshen gradually and there will be some rain moving in off the Atlantic sometime Tuesday or Wednesday.
